First, the Columbus facility's Biomass Fluid Catalytic Cracking, or BFCC, unit has completed its first uninterrupted 30-day run. Second, the facility made its first shipment of cellulosic gasoline on June 28, which represented the first fuel shipment since March, 2013. Lastly, the facility commenced regular shipments of both gasoline and diesel that same day.

"Commencing regular shipments of gasoline and diesel is very significant for KiOR, as it reflects the continuous improvements in our operations at the Columbus facility," said Fred Cannon, KiOR's President and CEO. "We have been undertaking considerable reliability and optimization efforts in areas of the facility unrelated to KiOR's core technology. The success of these efforts gives us confidence, more than ever, that the performance targets for the Columbus plant are attainable in the months ahead and that our operating assumptions for our next, larger Natchez plant are reasonable."

"With the facility operating stably and producing cellulosic gasoline and diesel at commercial scale, we believe we are on track to achieve steady-state operations before the end of the calendar year and to demonstrate improving performance metrics over that timeframe," Cannon continued. "The largest commercially producing cellulosic production facility in the world, we expect Columbus – enhanced with our recent optimizations – to be the basis of our second facility's design at Natchez."
